Types

type DBExecutor

type DBExecutor interface {
	QueryContext(ctx context.Context, query string, args ...any) (*sql.Rows, error)
	ExecContext(ctx context.Context, query string, args ...any) (sql.Result, error)
}

DBExecutor abstracts database operations for host functions.

type Registry

type Registry struct {
	// contains filtered or unexported fields
}

Registry holds the host-side resources that host functions can access. Each plugin instantiation creates a filtered view based on its manifest.

func NewRegistry

func NewRegistry(
	httpClient *http.Client,
	db DBExecutor,
	logger func(string),
) *Registry

NewRegistry creates a new host function registry.

func (*Registry) Close

func (r *Registry) Close() error

Close cleans up resources held by the registry.

func (*Registry) InstantiateModule

func (r *Registry) InstantiateModule(
	ctx context.Context,
	rt wazero.Runtime,
	manifest *capability.Manifest,
) (api.Module, error)

InstantiateModule creates a wazero host module exposing only the host functions allowed by the given manifest. If the manifest is nil or declares no capabilities, no module is instantiated (returns nil, nil).
